Is StarCraft II: Wings of Liberty going to make 2009? Blizzard isn't saying, sticking to the "it's done when it's done" release date. But there's definitely one big Blizzard-developed title in store this year.

What is it? Blizzard COO Paul Sams wouldn't confirm whether that game is, indeed, the first chapter of the StarCraft II trilogy, only confirming that "Blizzard intends on delivering one front line release per year." Activision Blizzard has factored that mystery game into its estimated earnings for 2009.

"You can see that is contemplated," Sams said during the company's earnings call. "Which title is being released this year, we're not saying."

Considering that StarCraft II appears to be the game closest to completion, we'd think the real-time strategy could make a 2009 release. Diablo III? No way. And while Blizzard did say it has "substantial expansions" planned for World of Warcraft this year, we'd find it hard to believe a retail expansion on par with Wrath of the Lich King will be ready for December.
